•No clear trend between scans

•Each scan was approximately 5 minutes long

•Approximately 200nA (electrons) continuous

•Standard Deviation is shown

•It would appear that each of these samples produces similar SEY

•B33 was tested in early January

•*Most likely candidate for visible peak(s)

•Data is shifted by about 7eV due to insulating-nature of glass

•Peak shift is not constant across entire spectrum due to insulating-nature of glass as well as chemical shifts

•Sb and As will not be resolvable for this sample due to interference with both O and Si

•B270 was not tested as a possible solution was found that determined which side of the glass was the float side

B33 Float Glass

This Week

• Will continue testing Al2O3 samples from our ALD group

• MatSci Division ISM-Day on Friday• Troubleshooting and hopefully fixing the

UV-light source– He plasma forms between anode and HV-

input rather than between anode and cathode.
